•Operation
General
The DPA/AVX allows you to set two independent trip points on a
AC voltage signal. The unit is normally set for 47-63 Hz frequency
sine wave signals but can be ordered with the /RMS option which
calculates the true rms voltage for non-sinusoidal waveforms.
Setup
The alarm relay coils operate according to each setpoint/deadband
configured via front panel multiturn potentiometers. Internal push
fit jumpers determine the alarm type (high or low acting) and coil
energisation (normally energised/de-energised).
